IMPROVEMENT IN -SIEM-WINDING WATCHES.

TO ALL WHOM IT MAY CGNCERN:

Be it known that I, ARTHUR Wanswoaru, of Newark, in the county of Essex,and State of New Jersey, have invented a new auduseful Improvement inWatches and I do. hereby declare that the following is s full, clear,and exact description thereof, which will enable those skilled the artto make and use the same, reference being hadto the accompanyingdrawings, forming part of this specification.

The present invention relates to that class of watches for the windingand setting of which no key is required, and in which both operationsare performed by simply turning the pendant to the watch-case; and thisinvention consists, rst, in an improvement upon the manner of hangingthe adjustable gears interposed between the pendant and the main-springaxis and-the handairbor, respectively, whereby their arrangement is muchsimplified and rendered more convenient in use; secoild, in combinationwith a pendant arranged to turn, a pusher so connected as to turn inconjunction therewith, and thus through it turn the main-spring axis orthe hand-arbor, accordingl to which is in connection with such pendant,while at the same time the pusher is free to play in and out for openingthe watch-case, as in watches opening through a p'usher; third, inapplying a packing-ring about the pusher and between it and the pendant,to prevent dirt and dust from passing through the same to the watchmovement. In the accompanying plate of drawings, my improvements inwatches" are illustlated- Figure I' being an inside view of the watchwith the dial-face or plat-e removed, showing the arrangement andconnection of parts between pendant and main-spring axis and hand-arborfor winding and setting.

Figure 2 is a section taken in the plane of the line :v z, iig. I, whichis across the watch-case, and in aline at right angles to the length anddirection of the pendant-pusher.

Figure 3, a plan or top view of the pusher, the pendaut-ring, and theportion of pendant inwhich the pusher is arranged to move.

Figure 4, a section through pendant, taken in the plane of the line y y,iig. I; and

Figure 5, a view of one face of the wheel with which the pendant isconnected, and through which the main-spring axis and hand-arbor areoperated by the intermediate gears between them and the said wheel,engaged with the pendant.

Similar letters of reference indicate corresponding parts.

A, in the drawings, represents the rim or body to a watch-case, B thependant, and C the pendant-ring; D, a plate secured in watch-case rim A,on which plate the parts for winding and setting are arranged, as willbe now explained. E, the main-spriug axis, carrying gear-wheel F ofsuitable size; G, the hand-arbor, also carrying gear-wheel H; I and I2,two gear-wheels of similar size. These gears I and I2 are hung to acommon bar, J, placed across the plate D at right angles to the lengthand direction of the pendant, and with its two ends projecting throughways a, cut in the flange b to the watch-case rim A. This bar J issecured to the plate D by a set-screw, c, that passes through alongitudinal slot, d, in the bar, bywhich screw and slot it is guided inits movement across the plate. The bar J is also so located as to haveits gear I in connection with the gear or main-spring axis with theother gear I2, through its concentric pinion d, secured to its underside, out of connection with the gearf andpinion g, interposedibetweenit and the gear to the hand-arbor; K, a bent spring, secured at one-endto the inside of the watch rim A, with its other end engaged with thecross-bar J, hereinbeL fore referred to. This spring, while acting tohold the gear Iz of the bar J disengaged from the train of gears betweenit and the hand-arbor, yet allows the said bar vto be moved suicientlyto bring the said gear I, by its pinion, into connection with thehand-arbor, and a gear-wheel, L, arranged to turn upon an axis of thewatchplate D, at the same time disconnecting the gear I from thegear-wheel L, just above referred to. With the gear-wheel L, bycrown-teeth upon its under side or face, as shown in iig. 5, a pinion,M, engages, which is secured to the lower end of a stem, N. This stem issecured in the pusher O to the pendant in a similar manner to thatdescribed in the Letters Patent hereinbefore referred to as granted tome, so that while the pusher can have a. lateral play upon such stem, iftheV pusher is turned such stem will be turned with it, and thus throughits pinion turning the gear with which it is connected, as has beenexplained. The pusher 0 extends through the pendant, projecting at itsouter end therefrom suiiiciently for its inward movement to operate thecatch= spring to the watch-caso ss in ordinary hunters watchesr Z,` arib along one side of pusher-0, by which rib vthe pusher is engaged witha corresponding shaped groove, m, in the portion P of the pendant, asshown in iig.

3 more particularly. This part P of the pendant is hung on the otherpart O, fixed to the watch-body A so that it can be turned aroundthereon,and thus, through it, the pusherl O, because of its connectionby a. spline- `ioint therewith, and through such pusher the pinion andother parts which may be in connection therewith. S, a. packing-ring ofrubber or other suitable material around pushei` O, and between it andthe pendant, to prevent dirt or dust from passing through the pendant tothe watch-movement. By the arrangement of' the bar J carrying the gearsI and I2, the main-spring can be wound at any time, Whether thewatch-case is opened or Y closed, by simply turning the pendant in theproper direction therefor, it being impossible to wind it in the Wrongdirection, even if the pendant is so turned, as the power exertednponthe wheel L and the connectinggear Ispends itself upon the spring R,that is connected with the bar T, causing the said gear I to turn uponthe wheelF to the main-spring axis without moving such Wheel. To set thehands the bar .I at its end T is first pressed inward suicient toestablish the necessary connection of parts lbetween them and thependant, at the same time breaking the connection between the pendantand the main-spring axis, and then the pendant turned to the right orleft, as maybe necessary.

I claim' as new, and desire to secure by Letters Patent-- 1. The bar J,carrying Wheels and I2, interposed between the pendant and the:nain-spring axis, and handarbor, respectively, of a watch-movement,substantially as and for the purpose described.

' 2. The combination of a turning-pendant and pusher, when connectedtogether in n. watch, substantially as described for the purposespecified.

3. The packing-ring s, or its equivalent, between'the pendant and pusherof a Watch-case, substantially as and for the purpose described. l

The above specification of my invention signed by me this 16th day ofMay, 1867.
